Hi all,
When developing a package, it's often useful to be able to reload it,
without re-installing, re-starting R and re-loading. To do this I've
written a little script that inspects the package description and
loads dependencies, data and code - http://gist.github.com/180883.
It's obviously
Nice. I would guess many of us would have versions of this, it would be good
to formalise it so that it could deal with :
- namespaces, you might want your unexported functions to be separate from
your exported functions. It looks like your function loads everything into
.GlobalEnv
- S4
Is this intentional? .r is accept most other places.
